FIELD
The present disclosure relates to a financial transaction card and, more specifically, to a financial card-enabled personal financial account management systems and methods.
BACKGROUND
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Financial cards are used by individuals and businesses for the payment of amounts owed for a purchase. These financial cards represent a financial account of that of a user with a financial institution wherein the user has opened an account and has agreed to reimburse the financial institution for transactions where the card is a credit card or the user agrees to prefund the account with a prefunded amount from which the purchases are subtracted where the card is a debit or prepaid card. Each of these cards includes a financial account number that is unique to that particular financial card and that uniquely identify the financial account of that particular user and card. Each financial account and/or financial card can also have an associated security code and/or personal identification number (PIN).
The user of the card presents the financial card either at the time of a purchase for processing using a point of sale transaction terminal that enters the account number and can also include entering the PIN or security code. A similar process is handled via manual input for on-line payment systems or to agents of third parties over the telephone. In this later case, the account number and possibly the PIN and security code are entered by the agent into a similar transaction processing system for providing such information for processing of the payment of a transaction amount. A centralized transaction processing system of the financial institution receives the financial account number and the security code or PIN from the transaction processing entity along with the identification of the payee, authorizes the payment, and arranges for the transfer of the transaction amount from the financial account of the user to the designated account or financial institution of the payee. The transaction amount is either deducted from the prepaid funds of the financial account of a user where the financial account and card are prepaid or debit accounts or is reflected as a credit purchase in the user's account for a credit account that is subsequently billed to the user for payment reimbursement to the user's financial institution.
Generally, these financial cards, the financial account, the transaction processing systems at the point of sale or entry and the transaction processing system of the financial institution are only capable of a single financial account and a single financial account number. As such, the user must manage their purchases and/or prefunding of the debit card account on a total account basis and can only allocate the purchases for personal financial management as a separate process individually. While users often have aided their management through opening of multiple accounts with the same or multiple financial institutions, these require different financial accounts and different financial cards, which is often not desirable to the user.
SUMMARY
The inventor hereof has succeeded at designing a financial card that enables per-transactional user definable magnetic encoding of a portion of the magnetic strip. Such financial card will enable users to manage their account on a per transactional basis by indicating user selectable subaccounts or other indicators that are read off the magnetic strip and processing by the transactional processing system and financial card issuing entity for offering new services to the financial card user.
According to one aspect, a financial card having a body with a front surface and a back surface and a primary account number associated with a primary account of a user of the financial card, the card including a magnetic strip positioned on the back surface configured for magnetic encoding including the primary account number. The magnetic strip includes a user definable portion for providing a selectable discretionary encoding thereto. The card also includes a user interface having at least one user input device positioned on the body of the financial card. The user interface is configured for receiving input from the user at a time of use of the financial card selecting a particular account indicator from among a plurality of account indicators each of which is associated with the primary account. The user interface is coupled to the user input device and to the user definable portion of the magnetic strip for providing the selectable discretionary encoding to the user definable portion of the magnetic strip responsive to the selected particular account indicator as received by the user interface at the time of use by the user.
According to another aspect, a financial card having a body with a front surface and a back surface and a primary account number associated with a primary account of a user of the financial card.

DETAILED DESCRIPTION
The following description is merely exemplary in nature and is not intended to limit the present disclosure or the disclosure's applications or uses. Before turning to the figures and the various exemplary embodiments illustrated therein, a detailed overview of various embodiments and aspects is provided for purposes of breadth of scope, context, clarity, and completeness.
As described herein, various embodiments of systems and methods for personal financial management using a financial card include a primary account with a plurality of subaccounts within the primary account. The subaccounts can be established by the financial institution but utilized by the user or owner of the primary account to aid and/or enable the user to personally manage their available funds by selecting a subaccount to apply a particular purchase and payment of a transaction amount. In some embodiments, this can also include prefunding of each subaccount for particular personal financial management purpose such as where applied in a debit card application. For example, a subaccount can be established for any reason that can aid a user of the card in management of their personal financials and in particular their expenditures to which the financial card is used. For example, subaccounts within the primary account can be established for items such as housing, rent, entertainment, food, groceries, restaurants, transportation, gasoline, clothing, children's expenses, home improvements, educational expenses, business expenses, discretionary expenditures, and savings, by ways of example.
The various systems for support of this financial account management system and method include a financial account management system that can be a centralized financial account management processing system of a financial institution which can be a credit card/debit card processing system. The system and method can also include transaction processing systems such as point of sale systems that are located at retail stores or seller vendor locations, or on-line via a web business or payment system for processing purchase payment transactions and payment of transaction amounts within the financial account management system from the user's account to a payees account. Additionally, a user payment device, such as a financial card, can provide not only the primary account number for the primary account of the user, but also can include, in some cases, the capability for the user to select on the financial card a particular subaccount to be used for a particular transaction payment, and then transference of the user selected subaccount indicator to the transaction processing system.
Referring now to FIG. 1, a personal financial management system 100 having a variety of different modules and components and embodiments is illustrated. As shown, a financial account management system (FAMS) 102 is configured for processing transactions from user selected subaccounts SAs as received from transaction processing systems 104. The FAMS 102 is configured to establish the primary account PA having a primary account number PAN and each having two or more subaccounts SA each of which has a separate subaccount indicator SAI. The subaccount indicator SAI can be any type of alphanumeric indicator and can be of any length. In one embodiment, there can be from 2 up to 10 subaccounts SAs, which can have subaccount indicators SAIs from 0 to 9, if a single subaccount indicator is desirable for system implementation.
Additionally, a maximum of 10 subaccounts SAs may be suited for many user applications. However, additional digits in the subaccount indicator can provide for more subaccounts SAs, such as 26 subaccount indicators SAIs if a letter in the alphabet is used or 100 subaccounts SAs if two digits are implemented for the subaccount indicator. The user U provides the FAMS 102 with the identification of the subaccounts SA, possibly a label or category for each, and in some cases a pre-funded amount or other rule or limits to each as will be discussed in greater detail below.
In some embodiments, the financial account management system 102 supports a pre-paid debit card that uses an industry standard card number but with a new personal identification number (PIN) that is segmented into a prefix or suffix for the subaccount indicator (SAD, such as a single digit in one embodiment, a card user created personal identification number PIN, and a subaccount indicator SAI. The subaccount indicator SAI can be a numeric digit inserted by the user in the prefix or suffix field that will logically link the corresponding purchase activity to one of the sub-accounts within the primary account PA. The financial account management system 102 includes programming that enables the financial institution offering the prepaid card service to recognize as valid any of the subaccount indicators SAIs to one of the predefined and prefunded subaccounts SAs. The financial services institution programming can further direct the payment transaction PT to one of the subaccounts SAs based on a digit entered in the prefix/suffix field and received and transmitted by a capable transaction processing system 104.
The payment transactions PT are identified by a subaccount indicator SAI associated with a single primary account number PAN in real time or near real time at the time of processing the payment of each transaction amount TA to a payee (PY) that in many cases originate at a cash register or purchase payment system 112 that transmits the payee identification number PID along with the transaction amount TA to the transaction processing system 104. Each payment transaction PT includes processing each transaction amount TA from the user selected prefunded subaccounts SAs by indicating at the time of each transaction a particular subaccount indicator SAI indicating the particular subaccount SA to be used for that transaction. The personal financial management system 100 can include a transaction processing system 104, 106, 108, which are generically referred to herein as transaction processing system 104, but also specifically referred to as transaction processing system 106 wherein the system is a point of sale transaction system 106 and as a transaction processing system 108 wherein the system in an online processing system such as a webpage or web portal payment system or third party agent on a telephone line that enters such transaction processing information.
A financial card 110 can be any type of financial card such as a debit or prepaid card. The primary financial account PFA typically has one or more financial cards 110 each having the primary account number PAN on the card. However, as described herein, each PA with PAN has associated with it a plurality of user defined and managed subaccounts SAs each having a user defined and selectable subaccount indictor SAI. The transaction processing systems 104 are configured to connect into a local user purchasing system to receive the transaction amount TA, and then receive from the user the primary account number PAN and the user selected subaccount indicator SAI at the time of purchase.
In some embodiments, the user can establish prepaid amounts or budget for each subaccount SA within the primary account PA and enables the user to designate at the time of a purchase which one of the plurality of subaccounts SAs to utilize for the particular purchase and payment of the associated transaction amount TA to the payee PY. However, as also noted, where a credit card embodiment is utilized, the subaccounts SAs are not necessarily prefunded, but there can be rules or limitations established for each credit card subaccount SA as a way of enabling the user to budget and manage within predefined credit expenditure levels.
The user designation of the subaccount SA can be provided, in one embodiment, by the user entering an additional subaccount indicator SAI, or wherein the user can enter it into a user interface of the financial card that is then input by the card into the transaction processing system 104 at the time of payment. The subaccount indicator SAI can be a character or digit or code encoded in digital bits that is separately entered or that is entered at the beginning or end of the user's PIN entry. The user designated subaccount indicator SAI is received by the transaction procession system and transmitted to the financial account management system 102 of the financial institution wherein payment transactions PT are processed. That system 102 manages the payment transactions PT based not only on the primary account PA, but also the subaccount SA within the primary account PA. The financial account management system 102 as addressed above includes subaccounts SAs that, in some embodiments, have had pre-funded or defined spending limits for each subaccount SA. In such embodiments, after the user pre-funds each subaccount SA that can be particular classifications or types of purchases or transactions, the user can designate the particular subaccount SA at the time of a payment transaction PT so as to personally and proactively manage their personal financials within the predefined limits or pre-established rules of the subaccounts SAs thereby enabling the user to not only budget for categories of spending, but also to manage those budgets in real time at the time of each and every transaction, to within limits or budgets for food, clothing, entertainment, gas/transportation, by ways of example. This can be useful, for example, where a third party such as a parent, provides the prefunding for each subaccount SA, whereby, a minor or student is provided a prefunded budget for each particular subaccount SA.
In some embodiments, a financial account management system 102 is configured for processing payment transactions PT from the user's primary account PA and specific subaccounts SA therein to payees PY, as indicated at the time of payment transaction PT by the user that provides the subaccount indicator SAI. The financial account management system 102 typically is located in a centralized location that is communicatively coupled or connectable to remotely located transaction processing systems 104 via network or communication facilities or services. As such, the financial account management system 102 includes a network interface 116 configured for interfacing with multiple transaction processing systems 104 over a variety of suitable communication network links 118. Any suitable protocol can be used and are common in the financial industry to provide secure transmission of financial information. This secure information includes, but is not limited to the identification of the transaction amount TA, the primary account number PAN, the subaccount indicator SAI, the user's name, and a payee identification number PID associated with the account to which the transaction amount should be sent. A database 118 within the FAMS 102 includes a plurality of primary accounts PAs for each of the many users of the financial institution and also includes each of the plurality of subaccounts SAs within each PA, along with each of their unique subaccount indicators SAIs. Wherein the application is a prefunded debit card embodiment, instead of not only providing the primary account PA with a prefunded amount, each of the subaccounts SAs can include prefunded subaccount amounts as prefunded budgets by subaccount for transaction processing of the user's expenditures within each subaccount. The financial account management system FAMS is configured for management and administration of the primary accounts PA and the subaccounts SAs within each primary account PA and their prefunded subaccount levels and transactions to and from such, including payments and transfers.
In these embodiments, the financial account management system 102 manages the funding and transactions in and out of the prefunded subaccounts SAs, and within the entire primary account PA. The system 102 receives payment transactions PT from various transactions processing systems 104 that identify the primary account PA by primary account number PAN and the subaccount SA by the subaccount indicator SAI, for payment of a transaction amount TA to the payee PY via a funds transfer interface 120 to a funds transfer operation or system 119 of the transaction payment TP that includes the transaction amount TA to the payee identification number PID of the party to be paid the transaction amount (TA). To accomplish this, the system 102 processes payment transactions PT with transaction amounts TA from each subaccount SA based on the received primary account number PAN, the received subaccount indicator SAI, the prefunded amount in the subaccount SA associated with the received subaccount indicator SAI and any rules established for the primary account PA or subaccount SA.
As also shown in FIG. 1, in one embodiment the user can utilize financial card 110A for a payment transaction PT. After making a purchase with payee PY, the payee PY completes the payment transaction PT of the transaction amount TA via the user's financial card 110A using a card reader 122 with the transaction processing system 106. The user can then enter the subaccount identifier SAI via a user interface 124 of the transaction processing system 106, either by itself, or in conjunction with the user entering of their PIN in the UI 124. As a second example, the financial card 110B may be configured with a financial card user interface 126 that enables the user to input a selection of a subaccount SA or the subaccount identifier SAI directly on the card 110B. In such embodiments, the user would present the financial card 110B to the card reader 122 wherein the card reader 122 would not only obtain the primary account number PAN, but also automatically obtain the subaccount identifier SAI, such as from the magnetic strip if a debit or credit card, or electronically from a Smart Card.
As described, one or more embodiments of the system as described herein can be utilized for performing a method of providing personal financial management to a user using the financial card 110. One embodiment of such a method includes establishing a primary account PA in the financial account management system 102 for payment of transactions based on a primary account number PAN and a prefunded amount for the primary account PA for a user U, as shown in FIG. 1. In addition to the primary account PA with a primary account number PAN, the user would also establish or create a plurality of subaccounts SAs within the primary account PA with each having a subaccount indicator SAI. Each can also have subaccount prefunded amounts within the prefunded amount of the primary account PA or have rules or limitations, in some cases. The method can also include receiving funding from the user for each of the subaccounts SAs and receiving a payment transaction PT (request for a payment) from the payee or payee purchase payment system 112 requesting payment of a transaction amount TA associated on behalf of the user. The payment transaction PT can include the transaction amount TA, the primary account number PAN, and a user selected subaccount indicator SAI. The user selected subaccount indicator SAI is one of the subaccount indicators SAIs within the primary account PA associated with the received primary account number PAN. The method further includes verifying the availability of funds in the subaccount SA associated with the received subaccount indicator SAI by the FAMS 102. The method includes transmitting a transaction authorization TransAuth to the transaction processing system 104 in response to a positive verification of available funds within the subaccount SA associated with the received subaccount indicator SAI.
When a payment transaction PT is being processed, if the financial account management system 102 determines that there is insufficient funds available for payment of the transaction amount TA from the user selected prefunded subaccount SA, the payment of the transaction amount TA from the primary financial account PA and the subaccount SA can be denied. However, in other embodiments, the financial account management system 102 can be configured to transmit a lack of funds indicator or message back to the transaction processing system 104 from which the payment transaction PT originated and therefore to the user. The user can then be prompted with an indication that insufficient funds are available from the previous selected subaccount SA. Additionally, the prompt or message can also include an indication that funds are available from a different or alternative subaccount SAAlt within the user's primary account PA. The financial account management system 102 can also prompt or transmit a request for the user at the transaction processing system 104 to select an alternative subaccount SAAlt from within the primary account PA rather than denying the processing of the payment transaction payment PT. The user can then reenter an alternative subaccount indicator SAIA at the transaction processing system 104 that is then retransmitted to the financial account management system 102 for payment processing using the alternative subaccount SAA within the primary account PA. For instance, the user may have set up a separate subaccount SA for discretionary or overage spending that has a separate subaccount indicator SAI or may chose to utilize a different subaccount SA for that particular transaction to allocate prefunded amounts or limits from one subaccount SA to a second subaccount SA for the particular payment transaction payment PT. The financial account management system 102 can manage and report these back adjustments or transfers to the user in their financial account statements of the primary account PA by listing the subaccounts SA and any issues or transfers related to one or more thereof In this manner, the user can separately track and manage each subaccount SA within the primary account PA.
In another embodiment, the financial account management system 102 can provide the user the ability to pre-establish subaccount rules or primary account rules that include rules that limit or prearrange for the transfer of funds between subaccounts SAs. This can address both real time user requests for payment transactions PT or can include automatic system generated alternative subaccount transfers or funding based such as when insufficient funds are in a first user selected subaccount SA for a particular payment transaction PT. This can also include limitations on the transfer of funds between subaccounts SAs even though sufficient funds may be available in other subaccounts SAs within the primary account PA, such to protect certain categories of funds, such as prefunded amounts for rent, housing or car payments, such funds being established as nondiscretionary for other use purchases or payment transaction PT. The financial account management system 102 can receive an allocation instruction from the user or a third party of the account, such as a parent or guardian, to form rules that are stored within the memory 128 as rule instructions 130, e.g., software encoded instructions. These rules 130 can include an instruction for the future reallocation of prefunded amounts from a first subaccount SA1 to a second subaccount SA2, both within the same primary account PA with the same primary account number PAN. The financial account management system 102 can also be configured to receive an instruction from the user via the transaction processing system 104 to cause a real-time transfer for the processing of the payment transaction PT of the transaction amount TA. In such cases, a special override code or authorization code can be required to be provided, as provided for by the rule instructions 130 and pre-established by the user. The financial account management system 102 would then verify the availability or validity of such an instruction and the availability of funds and if allowable and there is sufficient prefunded amount in the selected alternative subaccount SAA, the system 102 would process the payment transaction PT from the alternative subaccount SAA.
When operable in an integrated system, the financial account management system 102 can be configured for receiving the primary account PA for specifying a subaccount descriptive label for each of the subaccounts SAs within the primary account PA to aid the user in their personal financial management.
The financial account management system 102 is configured to compare the transaction amount TA with the prefunded amount or predefined credit limit associated with the subaccount SA of the received subaccount indicator SAI and determines the appropriateness of authorizing the payment transaction PT. A verification of available prefunded amounts is then transmitted to the transaction processing system 104 responsive to a successful determination of availability of prefunded amounts or available credit, or a lack of funds indication or indicator or message is transmitted to the transaction processing system 104 responsive to an unsuccessful determination of availability of prefunded amounts or available subaccount credit limit.
The prefunded debit card prefunding process can be supported by programmed logic to distribute or allocate dollar amounts to each of the subaccounts SAs within the primary account PA. Techniques employed to accomplish this prefunding distribution include allocating a percentage of the total to each sub-account or allow for an assignment of specific dollar amounts to each subaccount SA with a count-down feature for the remaining total addition to support the spreading of total dollars added to the subordinate subaccounts SAs. Additionally, as described herein, the system can enable the user to establish transactions rules that address the funding verification, denial or transfer of funds between subaccounts SAs that can be applied in real time during transaction processing. These and other embodiments will be described in more detail.
In some embodiments, the systems and methods can include a financial card 110 for use by the user that is configured specifically to receive user input specifying a particular one of the subaccounts SAs at the time of each purchase that will be used for payment of the particular payment transaction PT. The transaction processing systems 104 and the financial card 110 are configured for automatically transmitting and using the user specified subaccount SA as entered by the user on the financial card 110. Exemplary embodiments of various financial cards and transaction processing systems 104 for use with the financial card 110 will now be explained in more detail. In one embodiment referred to herein as Protect Our PocketTM personal financial account management system (a trademark of the inventor hereof), a pre-paid debit card can offer a user friendly method to the card holder to access each of one to ten subaccounts SAs within the primary account PA of a single debit card for the purpose of improving personal cash budgeting and management. The transaction processing system 104 that transacts with the financial account management system 102 for processing and approval of each payment transaction PT of the user at the time of use and provide for payment of the transaction amount TA from the user's subaccount SA within the primary account PA to the payee to which the user owes the transaction amount TA.
In some embodiments, the transaction processing system 104 is configured to transmit the transaction amount, the primary account number PAN and the received subaccount indicator SAI to the financial account management system 102. The transaction processing system 104 can be configured for initiating the payment of the transaction amount TA and providing the primary account number PAN to the transaction processing system 104. Such systems, such as point of sale systems 106, or online transaction processing system 108 are typically implemented by a retail seller or on-line seller or system.
The transaction processing system 104 as described herein can also be enabled through new and additional features and capabilities to the transaction processing systems 104, such as point of sale terminal 106 that are located in retail establishments or via on-line payment operators. One embodiment of such a point of sale transaction processing system 106 includes a card reader 122 configured for receiving a primary account number PAN from a debit card 110, a transaction interface 121 for receiving a transaction amount TA, a user interface is configured for receiving a user authorization, a debit card processing module 106 configured for processing of the received debit card information and the user authorization and a network interface 125 configured for communicating with the financial account management system 102 having a plurality of primary accounts PAs including a received primary account with prefunded subaccounts SAs.
The user interface 124 is configured to receive a user input identifying a particular one of the prefunded subaccounts SAs associated with the received prefunded primary account PA. The debit card processing module 106 is configured to receive the user input identifying the particular prefunded subaccount SA and to initiate a communication over the network interface 125 of the received primary account number PAN, the received user authorization, the received transaction amount TA, and the received particular prefunded subaccount SA.
In another embodiment of a transaction processing system 106 for use as a point of sale terminal as described herein, a point of sale terminal 106 includes a transaction interface 121 for receiving transaction information including a transaction amount TA from a purchase processing system 112. A card reader 122 is configured to read a financial card 110 having a primary account PA with a primary account number PAN associated with the financial card 110. The card reader 122 is also configured to receive a user selected subaccount indicator SAI from among a plurality of subaccount indicators SAIs, each of which is associated with a different subaccount SA within the primary account PA of the financial card 110. Of course, the card reader 122, having a user interface 124, can also be configured for receiving an input from the user that includes the subaccount indicator SAI and possibly also a Personal Identification Number (PIN). The transaction processing system 104 can also include a memory 127 and is configured with computer executable instructions for performing the transaction processing operations. A network interface 125 is configured to communicate with the financial account management system 102 for transaction authorization that includes transmitting the payment transaction PT information including the primary account number PAN, and the user selected subaccount indicator SAI to the system 102. If a PIN is also entered, the PIN can also be transmitted. The network interface 125 is also configured to receive a reply authorizing or denying or otherwise, as is described in greater detail herein.
In some embodiments, a transaction payment device 110 such as a financial card 110 can be implemented to enable the user to present the primary account PA and the subaccount indicator SAI to a transaction entity for payment of a transaction amount. Of course, in some embodiments, as described above, the user can enter the subaccount indicator (SAI) in the user interface 124 of the transaction processing system 104. The transaction payment devices 110 can include a debit card, a charge card or a smart card. For instance, when the transaction payment device 110 or financial card (herein referred to interchangeably) is a debit card, the financial card 110 can be configured to receive an input from the user that identifies one of the various available subaccounts SAs within their primary account PA that is to be used for the payment of the particular transaction amount TA. This can be done by the user providing a single subaccount indicator SAI associated with the selected subaccount SA to the transaction processing system 104 in conjunction with the providing of the primary account number PAN. In such embodiments, and as will be described in greater detail below, the transaction processing system 104 can be configured to receive not only the primary account number PAN and other standard user and financial card data, but also the subaccount indicator SAI.
One exemplary financial card 110 is illustrated in FIGS. 2A and 2B. As shown, the card has a body 150 having a front side 152 and a back side 154, a primary account number PAN positioned on the front side 152. Additionally, the front side 152 typically also includes an issuer identification 156, a text name 158 of the user to which the card is issued, and an expiration date 160. As shown in FIG. 2B, a magnetic strip 162 is positioned on the back side 154. As shown and described in this disclosure, the magnetic strip 162 has a predefined portion 164 and a user definable portion 166. The user definable portion 166 is configurable by the user at each time of use of the financial card 110 for payment of the transaction amount from a particular user selected subaccount SA. A signature block 168 is also typically included. The user definable portion 166 can include, as will be described below, a variable field that accepts for each use, a user selected subaccount identifier SAI from among the available subaccount identifier SAs within the primary account PA as identified by the primary account number PAN for the financial card 110. To accomplish this, the card 110 includes a card user interface 126 that is described in various exemplary embodiments in FIGS. 3, 4, 5 and 6. The user interface 126 of the card 110 can be configured for receiving a user selected subaccount indicator SAI and for configuring the user definable portion to include the received user selected subaccount indicator SAI.
As described above, the transaction processing system 104 can include the card reader 122 that is configured to read the financial card 110 having the magnetic strip 162 with both the predefined portion 164 and the user definable portion 166 for obtaining the primary account number PAN and, where applicable, the user selected subaccount indicator SAI directly from the magnetic strip 162.
As one example, the system and method as described herein can utilize existing international standards for financial cards and the coding of the magnetic strip 162 wherein the transaction processing systems 104 and their card readers 112 are similarly compliant. Generally, financial cards 110 are currently based on International Standards Organization (ISO) standard ISO 7813 that defines the magnetic coding for two of the three separate magnetic tracks on the financial card, e.g., tracks 1 and 2. ISO standard 4909 provides the formatting for track 3, which is sometimes but not often used. These standards define the formatting for the three magnetic tracks 170 (shown as a first track 170A, a second track 170B, and a third track 170C in FIG. 2B). The capabilities of the standard formatting for these tracks 170 can be utilized to enable the system of primary account PA with subaccounts SA as described herein. Some exemplary embodiments of such will now be briefly described by way of example. Generally, any of the three tracks can be used to with the present disclosure. A brief description will address Track 1 and Track 2 as these are typically used in financial cards 110.
As defined in ISO 7813, Track 1 170A is generally used with the International Air Transport Association (IATA) and stores more information than Track 2 170B that is used with the American Banking Association (ABA). However, many financial institutions utilize Track 1 170A rather than Track 2 170B, as it includes the name of the user embedded on the magnetic strip 162. However, more than one track can be encoded and used on each card 110 and can be read by the card reader 122. Track 1 170A includes the cardholder's name as well as primary account number PAN and other discretionary data and as described herein, can also include the user definable portion 166 that includes the subaccount identifier SAI. Track 2 170B is the track that is read by most automatic teller machines (ATMs) and credit card checkers, and can also include the user definable portion 166 with the subaccount identifier SAI to be used for the particular payment transaction PT. The ABA designed the Track 2 170B specifications and all world banks are expected to abide by its formatting. It contains the cardholder's primary account PAN, an encrypted PIN, and other discretionary data, in the predefined portion 164 and can include the subaccount identifier SAI within the user definable portion 166.
The Track 1 170A includes up to 79 ALPHA 7-bit (including parity) characters (alphanumeric) and is defined as a read only format. consistent with the present disclosure, Track 1 170A can include the following fields (in this order):

|SS|FC|PAN|Name|FS|Additional Data|ES|LRC|

    
    
        with each being defined as:
        SS=Start Sentinel “%” (1 character)
        FC=Format Code
        PAN=Primary Acct. Number (maximum of 19 digits in accordance ISO 7812).
        Name=26 alphanumeric characters max.
        FS=Field Separator “^”
        Additional Data=Expiration Date, offset, encrypted PIN, user definable portion 166 with the subaccount identifier (SAI), etc.
        ES=End Sentinel “?”
        LRC=Longitudinal Redundancy Check
    
    


The Track 2 Layout slightly differs but is as follows:

|SS|PAN|FS|Additional Data|ES|LRC|

    
    
        SS=Start Sentinel “;”
        PAN=Primary Acct. Number (maximum of 19 digits)
        FS=Field Separator “=”
        Additional Data=Expiration Date, offset, encrypted PIN, user definable portion 166 with the subaccount identifier (SAI), etc.
        ES=End Sentinel “?”
        LRC=Longitudinal Redundancy Check
    
    


The Track 3 170C Layout is similar to the layouts of Tracks 1 and 2, 170A and 170B, respectively, and is almost never used. The tracks 170 for the magnetic strip 162 are shown in more detail in FIGS. 3A and 3B. As shown in FIG. 3B, the user definable portion 166 includes user definable portions of tracks 170A, 170B, and 170C, which are denoted as tracks 170A′, 170B′, and 170C′. FIG. 3B also illustrates that the user definable portion 166 receives an input from a user definable control module for providing the subaccount indicator SAI to the user definable portions as tracks 170A′, 170B′, and 170C′. Of course, as will be explained in greater detail below, the user definable tracks 170A′, 170B′, and 170C′ can also include the End Sentinel and the LRC in some embodiments.
For the particular system described herein, an explanation will be described in more detail with regard to Track 2 170B formatting.
As described by the ABA, Track 2 170B uses up to 40 binary coded digits 5-bit (including parity) characters (numeric) including for the SS, ES and LRC.
The primary account number PAN is defined by ISO 7812 and consists of a first 6 digits that are used as the Issuer Identification Number. This can include a Major Industry Identifier (MII) of up to 2 digits, which can include: Institutions other than card issuers; Airlines; Travel and entertainment; Banking/financial; Financial institutions not registered by ISO; Merchandising and banking; Petroleum; Telecommunications; and Telecommunications administrations and private operating agencies.
The Issuer Identifier Number (IIN) is the next 3 to 5 digits identifying the issuer. In some cases the first digit indicates the length of the TIN or the responsibility of its assignment outside of ISO. If MII=9 then the first 3 digits are the country code (CC). The Individual Account Identification (IAI) is up to 12 digits in length. This number is assigned by the card issuing institution. A one digit Check Digit (CD) follows and is calculated using a Luhn formula for computing modulus 10 “double-add-double” check digit as is known to those skilled in the art to complete the primary account number PAN and to ensure accuracy of the number. Different companies use different codes. For example, one major credit card company has a variable number up to 16 digits while another major credit card company uses 13 or 16 digits including the check digit (CD).
The next field in the Field Separator (FS) that is 1 character in length. The next field is the country code (CC) which is 3 digits in length and is defined in ISO 3166. The next field is the Expiration Date (ED) in the 4 digit format: YYMM. Next, optional digits can include a Service Code (SC) of 3 digits. The first digit of the SC from 0 to 9 is used for interchange and technology for financial transactions including bilateral agreements with various countries.
The second digit of the SC is used for authorization processing with digits 1, 3, 5-9 being reserved for future use and 0 being for transactions that are authorized following the normal rules; 2 being for transactions as authorized by the issuer and should be online, and 4 being for transactions as authorized by the issuer and should be online, except under bilateral agreement.
The third digit of the SC is for the range of services and PIN requirements, including: No restrictions but a PIN is required; No restrictions; Goods and services only (no cash); ATM only and PIN required; Cash only; Goods and services only (no cash) and PIN required; No restrictions and require PIN when feasible; and Goods and services only (no cash) and require PIN when feasible. If this field in not used a Field Separator FS is used.
Next, a PIN Verification Value (PVV) field of 5 digits is used by some financial institutions. Finally, the remaining characters on Track 2 are used for Discretionary Data that includes the Additional Data such as the Expiration Date 160, an encrypted PIN, and the user definable portion 166 that includes the subaccount identifier (SAI). Finally, the coding of the track 170 of magnetic strip 162 ends with a 1 character End Sentinel (ES) and a 1 character Longitude Redundancy Check (LRC). As the LRC addresses the entire coding of the track 170 that includes both the predefined portion 164 that is established by the card issuer and the user definable portion 166 that is encoded by the user with each use of the card 110 for defining the particular subaccount SA via a subaccount identifier SAI to be used for the particular transaction, the user definable portion 166 can also include the End Sentinel and/or the recalculated adaptable longitudinal redundancy check LRC that is required for processing and compliance with the ISO standards for the track formatting. In other words, an adaptable LRC is determined for each of the subaccount identifiers (SAI) selected by the user to ensure that the encoding of the magnetic strip 162 and in particular each magnetically encoded track 170 is encoded with the user definable portion 170′ that is appropriate to ensure proper reading and processing of the magnetic information on the financial card for each and every use of the card.
Referring now to FIGS. 4A and 4B, a financial card 110 suitable for use with the present disclosure systems and methods, can include a card user interface 126 that is comprised of blister buttons 174 positioned on one of the sides 152 or 154 (practically will be the front side 152) of the body 150 of the card 110. Each blister button 174 can be formed on a surface and within the card 110 and connected and include an electronic interface (not shown) to the user definable controller 173 for providing the selection of a particular blister button input from the user to specify the particular subaccount identifier to the user definable portion 166. The card user interface 126 receives the user selection when the user presses one of the blister buttons 174 at the time of purchase and prior to swiping the card 110 with it magnetic strip 162 in the card reader 122 of the transaction processing system 104. The controller 173 receives the user input from the selected blister button input, and creates the internal electronic circuitry operations, encodes via selectively magnetic energizing the user definable portion 166 to include the information on the desired user definable tracks 170A′, 170B′ and 170C′ that includes the user selected subaccount identifier SAI. When the user pushes another blister button 174 of the card user interface 126, the controller 173 creates operations for encoding the new user input for the information on tracks 170′ of the user definable portion 166 for the next payment transaction PT.
As shown in FIG. 4B, the blister buttons 174 can include indicia 176 on the card 110 that provides a textual description of the expenditure category thereby enabling the user to select the subaccount SA without having to remember the subaccount identifier SAI at the time of the transaction. All the user needs to do is to push the blister button 174 with the describing indicia 176 for the particular purchase. The controller 173 can determine the appropriate composing and encoding of the user definable portion as described above.
As noted, in some embodiments a financial card has a body with a front surface and a back surface and a primary account number associated with a primary account of a user of the financial card. The card has a magnetic strip positioned on the back surface configured for magnetic encoding including the primary account number. The magnetic strip includes a user definable portion for providing a selectable discretionary encoding thereto. The card also includes a user interface having at least one user input device positioned on the body of the financial card. The user interface is configured for receiving input from the user at a time of use of the financial card for selecting a particular account indicator from among a plurality of account indicators each of which is associated with the primary account. The user interface is coupled to the user input device and to the user definable portion of the magnetic strip for providing the selectable discretionary encoding to the user definable portion of the magnetic strip responsive to the selected particular account indicator as received by the user interface at the time of use by the user.
In some embodiments, the magnetic strip includes at least track 1 170A and track 2 170B of encoded data consistent with ISO standards. In such embodiments the user definable portion of the magnetic strip can be operably coupled to the user interface for defining the user definable portion to include the particular account indicator in the additional data field of at least one of track 1 170A and track 2 170B.
The selectable discretionary encoding can include one or more definable bits. In some embodiments, one or more selectable magnetic energizing devices, such as micro-energizable electromagnets, can be positioned proximate or behind the user definable portion 166 of the magnetic strip 162 and in particular the user definable tracks 170A′, 170B′, and/or 170C′. The selectable magnetic energizing device can be any suitable device for imparting a selective electrical encoding of a bit or bits to the user definable tracks 170A′, 170B′, and/or 170C′ as know to those skilled in the art. In one embodiment, the selectable magnetic energizing devices can be a one or more magnetic coils positioned behind the magnetic strip on the back surface of the body of the card. Each selectable magnetic energizing device can be configured to provide an encoding of a single definable bit of the selectable discretionary encoding. Each selectable magnetic energizing device can be selectably magnetically energized responsive to the received user input selecting the particular account indicator.
For example, in one embodiment, there are ten (10) buttons and ten (10) associated characters therewith and each character is encoded with five definable bits using five selectable magnetic energizing devices. The five bits can include 4 character defining bits and a parity bit. However, those skilled in the art will recognize that other quantities and arrangements are also possible and within the scope of the present disclosure.
In some embodiments, the user definable portion includes an adaptable longitudinal redundancy check (LRC) encoding having five LRC bits, for example. Each of the user input devices is coupled to a different selectable magnetic energizing device. One or more selectable magnetic energizing devices can be associated with a different one of the LRC bits. The different selectable magnetic energizing devices are positioned proximate to the user definable portion of the magnetic strip for providing the adaptable LRC encoding to the user definable portion of the magnetic strip. Such selective encoding is responsive to the selected particular account indicator as received by the user interface at the time of use by the user and to provide a proper LRC encoding to the magnetic strip of the financial card that includes all of the information on the track 170 including the user definable portion 170′ with the encoded user selected particular account indicator.
One exemplary embodiment of a user definable selectable magnetizing circuit 800 for the financial card 110 with blister buttons 174 is illustrated in FIG. 8. As shown, the user interface 126 includes ten (10) user input devices in the form of blister buttons 174 as described above. Each blister button 174 as shown in the user definable selectable magnetizing circuit 800 is operative coupled to selectably magnetize one of the user definable track portions 170′. The magnetic strip 162 includes the predetermined portion 164 and the user definable portion 166. The user definable portion 166 includes the user definable track portion 170′ that is shown in FIG. 5 to be a single track, track 2 170B with a user definable track portion being 1703. The user definable track 2 portion 170B′ includes, but is not limited to, a single account indicator character 806 that is encoded by five bits 808A-E for selectively encoding of an account indicator, such as the subaccount indicator (SAT), by way of example. Each blister button 174 is associated with a particular predefined account indicator character 806.
Each bit 808 of user definable or selectable account indicator character 806 includes one or more magnets 804, such as described above, for encoding thereof. As shown in this example, each bit 808 is defined by two magnets 804A and 804B. However, a single energizable magnet 804 is also possible as described herein. Each button 174 is operatively coupled to the bits 808 via bit magnetization controllers 814 for controlling and/or otherwise energizing magnets 804. The magnets 804 can be operatively positioned behind the magnetic strip 162 for selectively magnetizing the encoding of the user definable track 2 170B′. The bit magnetization controllers 814 are illustrated in FIG. 8 as D1P through D0P. In this example, the account indicator character 806 is defined with the bits 808 to include a first bit 808A, a second bit 808B, a third bit 808C, a fourth bit 808D, and a parity bit 808E. Each of these is controlled by two bit selectively magnetized magnets 804A, 804B for encoding the bit 808 as either a one or a zero. The bit magnetization controllers D01 and D11 are coupled to first bit 808A for selectively energizing first bit 808A as required to encode the user selected account indicator character 806 as selected by the user activating the buttons 174 of user interface 126. The second bit 808B, third bit 808C and fourth bit 808D are similarly associated with bit magnetization controllers as illustrated. Additionally, the parity bit 808E is selectably magnetized by bit magnetization controllers D0P and D1P as required to encode the appropriate parity to the encoded character 806.
A similar coupling, control, energizing and selectable encoding of the Longitudinal Redundancy Check (LRC) is also shown in FIG. 8 responsive to each user selected account indicator as received by the user interface 126 by activation of one of the buttons 174. As discussed above, an adaptable Longitudinal Redundancy Check (LRC) character 810 must be specified and encoded on the track 2 170B user definable portion 170B′ responsive to the user selecting a variable account indicator via activation of a button 174. The LRC must be adapted to ensure compliance of the each user selected account indicators with the industry standard ISO 7813 so that the magnetic strip 162 can be read by a card reader and the encoded information extracted therefrom for processing of the financial transaction using the card 110.
In this example, LRC character 810 is encoded by LRC bits 812A-812E. This includes a first LRC bit 812A, a second LRC bit 812B, a third LRC bit 812C, a fourth LRC bit 812D, and an LRC parity bit 812E. Each of these LRC bits 812 is energized by activating or energizing magnets 804A and 804B as described above. Each of these LRC energizing magnets are controlled by a mated pair of LRC bit magnetization controllers 818 that are shown as L01 through L11.
In operation of the circuit 800, a user accesses the user interface 126 at the time of a transaction and selects or activates one of the ten buttons 174. When the button is selected, the wiring 816 for that button sends control signals (not shown) to the operatively coupled bit magnetization controllers 814 for selectively encoding the associated account indicator character 806. The associated account indicator bits 806 are energized as either a one or a zero to selectably magnetize or energize the user definable portion 170B′ of track 2 170B to reflect the appropriate account indicator character 806. At the same time, the selected button 174 activates the associated LRC bit magnetization controllers 818. The LRC bit magnetization controllers 818 associated with the user selected account indicator character 806 for determining the correct adaptable LRC encoding of the user magnetic track 2 170 are then activated and/or energized. The LRC bit magnetization controllers 818 control the activation of magnets 804A and 804B for each LRC bit 812 to selectively encode the adaptable LRC character 810.
It should be recognized by those skilled in the art that the circuit 800 of FIG. 8 is just one embodiment, and other embodiments for selectively energizing the magnetic tracks 170 of magnetic strip 162 with the character 806 and the LRC 810 are also within the scope of the present disclosure.
As shown illustrated in FIGS. 4A and 4B to carry a charge to change the polarity of the 5 bits comprising a discretionary digit or character bit within the definition of additional data of Track 2 and the 5 bits comprising the LRC (Longitudinal Redundancy Check) as defined in ISO 7813.
The blister buttons identified by characters/digits 0 through 9 are displayed vertically down the center of the chart. Bit 0 through Bit 3 and a Parity bit for the discretionary digit are labeled D11 through D1P for the polarities representing a 1 and D01 through D0P for the polarities of 0. Bit 0 through Bit 3 and a Parity bit for the LRC are labeled L11 through L1P for polarities representing 1 and L01 through L0P for the polarities of 0.
FIGS. 5A, 5B, and 5C illustrate additional embodiments of a card 110 having various user interfaces 126 and various controllers 173 for composing the user definable portion 166 of the magnetic strip 162 for use with the present disclosure.
As shown in internal portions 178 of the card 110, FIGS. 5A, 5B, and 5C shows the interworkings of the card user interface 126 that include one or more rotatable wheels 180 that rotate on a pivot 182 embedded within the body 150 of the card 110. The magnetic strip 162 include a mechanically adjustable portion 184 associated with the user definable portion 166, and in this example, includes a variety of predefined user selected portions 186 each of which is pre-coded with a user definable portion 166 corresponding to one of the subaccount identifier SAI as selected by the user by rotation of the wheels 180. One of the wheels 180 can be a user input wheel 180A that is the card user interface 126 and that is rotatable by the user to select one of the subaccount indicators SAIs. By so operating the user input wheel 180A, the corresponding predefined user selected portion 186 is moved into the position of the user definable portion 166 of the magnetic strip 162 so that the appropriate tracks 170A′, 170B′, and 170C′, are positioned for reading of the user selected subaccount identifier SAI. FIG. 5B illustrates embodiments wherein there are multiple wheels 180, each being gears and coupled together for movement of the predefined portions 164 of the magnetic strip 162.
FIG. 5C illustrates another embodiment. As shown, the wheel 180 has spaced apart magnetic sections 190 each having an end 191 containing a different predefined user definable portion 186 having the user definable tracks 170A′, 170B′, and 170C′, that can be positioned with the magnetic strip 162 and aligned with predefined portion 164 and its predefined portions of tracks 170A, 170B, and 170C, for providing the user definable portion 166 with the user selected subaccount identifier SAI. Each spaced apart magnetic section 190 can be, for example, a paddle having the magnetic section 190 positioned on the free end 191. The magnetic section 190 includes the user definable portion 166 each having one of the subaccount indicators SAIs and possibly can also include any necessary sentinel character SC and the required adaptable longitude redundancy check LRC character.
The body 150 of the card 110 can include the wheel 180 that has an aperture 192 that is dimensioned for receiving a key (not shown) or other mechanism for enabling the user to rotate the wheel 180, such as with a finger or finger nail of the user. While not shown, the wheel 180 can be restricted in various manners from arbitrarily moving or rotating without user input, such as known to those skilled in the art. The wheel 180 can be selectively held in place after positioning by the user, either by friction or possibly a selective or limited locking portion or stop mechanism that can include a ratchet or similar device. In this manner, the wheel 180 is held in place until the user intentionally makes a change to the subaccount to be used for the next transaction. Additionally, each spaced apart magnetic section 190 can include indicia 194 that can be visible to the user for aiding in selection of the subaccount SA for the particular payment transaction PT.
As shown in FIG. 6, a display window 196 can be positioned on the front 152 of the card 110 proximate to one of the wheels 180 such that indicia 194 on one of the wheels 180 is visible to the user of the card 110 at the time of each use. The indicia 194 can be the subaccount indicator SAI or can be a textual description or a symbol or drawing indicating the subject matter of the subaccount. This can aid the user in selecting the subaccount SA at the time of use of the card 110 and therefore in managing their personal financials.
In other embodiments while not shown in the figures, the financial card 110 as described herein is a smart card. In such embodiments, the card reader 122 is configured to receive from the smart card 110 the primary account number PAN and the user selected subaccount indicator SAI. In one such exemplary smart card embodiment, a financial transaction card 110 includes a body 150 and an integrated microprocessor (not shown but known to those skilled in the art) and memory including a primary account number PAN having a plurality of subaccounts SAs, each subaccount SA having a different subaccount indicator SAI. A user interface 124 is configured to receive a user selection of one of the subaccount indicators SAIs and providing the user selected subaccount indicator SAI to the integrated microprocessor. An output interface (not shown but know to those skilled in the art) is configured to provide the primary account number PAN and the user selected subaccount indicator SAI to the transaction processing system 104 that is configured for processing smart cards for user transactions.
It should also be understood that while the exemplary embodiments as described herein relate to prefunded primary account PA and subaccounts SAs, the systems and methods hereof can also be suitable for use with credit card payment and processing systems 104. The primary difference in such embodiments is that there is not necessarily a check on the amount of prefunded amounts in a subaccount. However, as described herein, the user can establish subaccounts limits within his primary credit card account or credit card limit, and in such a manner, can personally manage his credit and/or expenditures. This can also be utilized to aid in the user allocating and managing his credit expenditures at least with regard to subdividing his monthly statements into subtotals or allocations on his monthly billing statements.
The transaction amount for a purchase by the user is determined at the point of sale that can include an on-line transaction processing system 108 or third party agent who enters the payment transaction PT information. The on-line transaction processing system 108 includes a communication interface 132 that can be a telephone line or a web portal or webpage. The user provides the primary account PA, and the subaccount indicator SAI to complete the payment transaction PT and the payment of the transaction amount TA from the user selected subaccount SA. As described above, the user can provide the subaccount indicator SAI either verbally, or via the communication interface 132 such as an entry into a webpage. Of course other user information can also be provided such as may be required for the particular application. The on-line processing system 108 processes the payment transaction PT in a similar manner as described above, including the provision of the subaccount identifier SAI as provided by the user for use with the particular payment transaction PT.
The transaction processing system 104 is configured to receive a personal identification number having at least one variable character selected by the user from among a plurality of available variable characters each of which is associated with a different subaccount. The financial account management system is configured to receive the personal identification number (PIN) from the transaction processing system 104 to verify the payment of the transaction amount from the primary account PA and from the subaccount responsive to the received personal identification number.
The herein the transaction processing system 104 is an online internet-based payment transaction system having a hosted user interface configured for prompting the user to input both the primary account PA and the particular subaccount for payment of the transaction amount.
The transaction processing system 104 is configured to receive a personal identification number at the time of the payment transaction PT, the personal identification number having two portions, a fixed predefined portion and a user definable portion, the user definable portion being user defined at the time of the transaction for specifying one of the available subaccount indicators SAIs.
The transaction processing system 104 is configured to receive the subaccount indicator SAI, an associated end sentinel character, and the adaptable longitude redundancy check (LRC) character.
As described, the various user financial cards 110 for personal financial management can include using a debit card. To accomplish this, the user would open a debit card primary account PA having a primary account number PAN with a financial institution. The financial institution would then issue to the user. The financial institution would issue a suitable financial card 110 to the user. At the same time, the user could establish a plurality of subaccounts SAs within the primary account PA with each being uniquely identified with a separate subaccount indicator SAI. The client and/or financial institution would then provide for a prefunding of each of the subaccounts SAs and maintain such prefunding on a monthly or bi-monthly pre-funded amount. The method also includes selecting one of the subaccount indicators SAIs for use as payment of a transaction amount TA. A payment of a transaction amount TA is initiated from the primary account PA using the debit card 110 along with the user selected subaccount indicator SAI.
Referring to FIG. 7, an operating environment for an illustrated embodiment of the transaction processing system 104 and/or the financial account management system 102 can include, in one embodiment, a computer system 700 with a computer 702 that comprises at least one high speed processing unit (CPU) 704, in conjunction with a memory system 706 interconnected with at least one bus structure 708, an input device 710, and an output device 712. These elements can be interconnected by at least one bus structure 712.
The illustrated CPU 704 is of familiar design and includes an arithmetic logic unit (ALU) 714 for performing computations, a collection of registers 714 for temporary storage of data and instructions, and a control unit 716 for controlling operation of the system 700. Any of a variety of processors, including at least those from Digital Equipment, Sun, MIPS, Motorola, NEC, Intel, Cyrix, AMD, HP, and Nexgen, are equally preferred for the CPU X. The illustrated exemplary embodiment operates on an operating system designed to be portable to any of these processing platforms.
The memory system 706 generally includes high-speed main memory 720 in the form of a medium such as random access memory (RAM) and read only memory (ROM) semiconductor devices, and secondary storage 722 in the form of long term storage mediums such as floppy disks, hard disks, tape, CD-ROM, flash memory, etc. and other devices that store data using electrical, magnetic, optical or other recording media. The main memory 720 also can include video display memory for displaying images through a display device.
